Originally known as Alexandra de noche (Alexandra at night) the show premiered on January 13, 2014, and aired weekdays at the 10:30 p.m. spot right after the nighttime edition of Telenoticias. The original version of Alexandra de noche followed the late-night talk show and had a half hour duration. During the show, Fuentes would open with a short monologue followed by an interview with a guest which would fill the rest of the program. The show debuted to moderate success for the station getting a ratings boost for the late-night spot and coming in second place behind WAPA-TV.[2][3]
